I had really bad health anxiety at one time, Peter. It's much better now. What I learned was by asking others opinions and by googling symptoms I was keeping myself unhealthy because I was telling my brain something was wrong by doing the very things to try to make myself feel better.

Trigger > anxiety > research > temporary relief, then it the anxiety would start again.

I started to find ways to prevent myself from talking about my worries and from googling. That's the only way I was able to overcome the health anxiety.
